PROBLEM TO BE SOLVED: To perform observation on a target making a motion different from direct advance, and also on a target whose posture changes during advance.SOLUTION: An image radar device comprises: a target observation circuit 3 for observing a target while changing an observation direction on a target reference coordinate system; a radar position acquisition circuit 1 for acquiring the temporal change of the position of the radar device; a target position acquisition circuit 2 for acquiring the temporal change of the position of the target; a target posture estimation circuit 4 for estimating the temporal change of the posture of the target on the basis of the temporal change of the position of the target; an observation direction estimation circuit 5 for estimating the observation direction of the radar device on the target reference coordinate system on the basis of the temporal changes of the positions of the target and radar device and the temporal change of the posture of the target; and a radar image reproduction circuit 6 for generating a radar image from observation results on the basis of the observation direction of the radar device on the target reference coordinate system. |
